I think that the FBT is bad and it is the cause for overloding that
diode in the PSU.
This is an usual scenario for old Monitor Hardware, nothing new.
The Epoxy in the FBT gets hard and brittle over the time and therefore
it cracks internally..causing winding shorts or opens.
Look if you can get an replacement FBT somwehre on the surplus market.
Please post all the numbers on the FBT-Label..if any exists.
